.SYNOPSIS...
FOLLOWING A WINDY AND VERY MILD AFTERNOON ACROSS THE NORTH
COUNTRY...TEMPERATURES WILL GRADUALLY COOL DOWN THIS EVENING UNDER
PARTLY CLOUDY SKIES. A COLD FRONT WILL BRING PERIODS OF SNOW
SHOWERS AND POSSIBLE SNOW SQUALLS AFTER MIDNIGHT WITH A MORE RAPID
FALL IN TEMPERATURES TOWARD MORNING. WINDS WILL REMAIN MODERATELY
STRONG AND GUSTY FROM THE WEST...SHIFTING INTO THE NORTHWEST
TOWARD MORNING. MOUNTAIN SNOW SHOWERS WILL CONTINUE THROUGH MUCH
OF SATURDAY WITH TEMPERATURES HOLDING IN THE 20S. AFTER A FAIR AND
QUIET DAY SUNDAY...A FAST-MOVING AREA OF LOW PRESSURE MOVING FROM
THE OHIO VALLEY EASTWARD ACROSS SOUTHERN NEW ENGLAND WILL BRING
LIGHT TO MODERATE SNOW SUNDAY NIGHT INTO MONDAY. COLD WEATHER IS
EXPECTED FOLLOWING THIS SYSTEM EARLY NEXT WEEK.
&&
.NEAR TERM /UNTIL 8 AM SATURDAY MORNING/...
AS OF 308 PM EST FRIDAY...WIND ADVISORY CONTINUES FOR THE NRN
ADIRONDACKS AND ST. LAWRENCE VALLEY WITH WEST WINDS 20-30 MPH AND
GUSTS 40 MPH TO LOCALLY 50 MPH. HAVE ALREADY SEEN A FEW GUSTS 40+
MPH AT SLK/MSS...AND LIKELY STRONGEST ALONG THE ERN SLOPES OF THE
ADIRONDACKS. STRONG GRADIENT FLOW AND STEEP LAPSE RATES WILL
PROMOTE GOOD DOWNWARD MIXING THRU THIS EVENING...THOUGH SLIGHTLY
BELOW WIND ADVISORY CRITERIA ACROSS VT. MAY SEE SOME STABILIZATION
OF PBL TOWARD MIDNIGHT...BUT A SECONDARY COLD FRONT PASSAGE 06-09Z
WILL LIKELY YIELD ANOTHER "SURGE" OF STRONGER WIND GUSTS AND
EXPECTED SNOW SQUALL ACTIVITY WITH THE BNDRY. WILL MONITOR SQUALL
POTENTIAL CLOSELY OVERNIGHT...BUT RIGHT NOW EXPECTING A QUICK 1-3"
OF SNOWFALL MOST SECTIONS DURING THE PRE- DAWN HOURS WITH STRONG
FRONTAL ASCENT...AND GOOD DENDRITE SNOW GROWTH. TEMPS WILL FALL
RAPIDLY TOWARD MORNING...INTO THE LOW TO MID 20S ACROSS VT AND
LIKELY INTO THE MID-UPR TEENS IN NRN NY. QUITE A DROP AFTER HIGHS
IN THE 50S MONDAY AFTN! HAVE PLACED POPS IN THE LIKELY TO
CATEGORICAL RANGE 06-12Z WITH GOOD DYNAMIC FORCING ALONG BNDRY.
COULD SEE BRIEF PERIOD OF VSBY BELOW A HALF MILE WITH SNOW SQUALL
ACTIVITY.
SO...QUITE A CHANGEABLE NEXT 12-18 HRS. CERTAINLY CONDITIONS WILL
REMAIN MILD AND WINDY THRU THIS EVENING FOR THOSE WITH OUTDOOR
PLANS. ANY WINTRY CONDITIONS WILL OCCUR NEAR/AFTER MIDNIGHT. WILL
ALSO NEED TO WATCH FOR PATCHY ICE FORMATION ON ROADWAYS/SIDEWALKS WITH
REFREEZING OF SNOWPACK AND ANY STANDING WATER TOWARD DAYBREAK
SATURDAY.
&&
.SHORT TERM /8 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/...
AS OF 308 PM EST FRIDAY...STRONG LOW-MID LEVEL NW GRADIENT FLOW IN
PLACE ACROSS THE NORTH COUNTRY DURING THE DAY SATURDAY WITH
CONTINUED LOW-LEVEL CAA REGIME. STEEP LOW-LEVEL LAPSE RATES WILL
CONTRIBUTE TO SFC NW WINDS 20-30 MPH WITH GUSTS AROUND 40 MPH.
COULD CONTINUE TO SEE A FEW GUSTS UPWARD OF 45 MPH...SO WIND
ADVISORY CONTINUES THRU 6PM FOR NRN NY COUNTIES. PERIODS OF SNOW
SHOWERS WILL CONTINUE...MAINLY ACROSS THE MTNS WITH ADDITIONAL
ACCUMULATION POSSIBLE. HIGHER ELEVATIONS SHOULD SEE 3-5" SNOW
TOTALS BETWEEN THE FRONTAL SQUALLS FRI NIGHT AND OROGRAPHIC SNOW
SHOWERS DURING THE DAY SATURDAY. LOWER SNOW AMTS ARE EXPECTED IN
THE VALLEYS. TEMPERATURES WILL LIKELY NOT RISE MUCH DURING THE
DAY...HOLDING MAINLY IN THE LOW TO MID 20S EXCEPT IN THE UPR TEENS
ACROSS NRN NY. THIS REPRESENTS A COOL DOWN OF 30+ DEGREES COMPARED
TO OBSERVED HIGH TEMPERATURES ON FRIDAY...AND WITH THE STRONG
WINDS...THE DIFFERENCE WILL FEEL EVEN MORE SIGNIFICANT.
NWLY GRADIENT FLOW RELAXES SATURDAY NIGHT WITH DIMINISHING SNOW
SHOWER ACTIVITY IN THE MTNS...AND JUST A FEW LINGERING FLURRIES
AFTER MIDNIGHT. TEMPERATURES SHOULD FALL INTO THE SINGLE DIGITS
FOR LOWS. SUNDAY SHOULD BRING BE A PLEASANT WINTER DAY WITH SFC
RIDGE AXIS MVG EWD AND CRESTING OVER THE NORTH COUNTRY DURING THE
AFTN HOURS. POTENTIAL TO SEE SOME SUNSHINE ON SUNDAY. TEMPS WILL
ONLY REACH THE 20S FOR HIGHS...BUT WINDS SHOULD BE LIGHT IN VCNTY
OF HIGH PRESSURE.
SREF/GFS/NAM MODELS REMAIN CONSISTENT WITH NEXT WAVE OF LOW
PRESSURE TRACKING EWD FROM THE OHIO VALLEY/SRN GREAT LAKES REGION
EWD INTO WRN PA/WRN NY BY 12Z MONDAY. THIS SYSTEM SHOULD YIELD
RAPID INCREASE IN CLOUDS SUNDAY EVENING WITH SNOW DEVELOPING
DURING SUNDAY NIGHT...MAINLY AFTER MIDNIGHT. BEST WAA/ISENTROPIC
ASCENT IS FOCUSED ACROSS SRN ZONES BASED ON CURRENT
INDICATIONS...SO FOCUSED POPS 60-75 PERCENT THERE...AND LOWER POPS
NORTH. SNOW CONTINUES INTO THE DAY MONDAY...WITH POSSIBLE 3-6" FOR
SRN HALF OF CWA...AND PROSPECTS FOR 2-4" SNOWFALL ACROSS NRN
HALF OF CWA.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
AS OF 245 PM EST FRIDAY...MONDAY WILL BE THE MOST ACTIVE DAY OF
THE EXTENDED FORECAST WITH LOW PRESSURE MOVING JUST SOUTH OF OUR
CWA. SNOW WILL CONTINUE ACROSS THE NORTH COUNTRY MONDAY AND THE
FIRST PART OF MONDAY NIGHT BEFORE ENDING. AFTER THIS SYSTEM
PASSES EAST OF THE REGION...SURFACE HIGH PRESSURE WILL RIDGE OVER
THE AREA THROUGH EARLY THURSDAY MORNING. THEN ANOTHER WAVE OF
MOISTURE MOVES ACROSS OUR FORECAST AREA THURSDAY AFTERNOON AND
THURSDAY NIGHT...BRINGING OUR NEXT CHANCE FOR SNOW SHOWERS. ECMWF
AND GFS HANDLE THIS SYSTEM QUITE DIFFERENTLY AT THIS TIME...BUT
AT OVER 150 HRS OUT CAN NOT PLACE MUCH CONFIDENCE IN EITHER
MODEL. DETAILS WILL BECOME MORE CLEAR AS WE GET CLOSER TO THAT
TIME FRAME. THE FIRST FEW DAYS OF THE EXTENDED FORECAST WILL
FEATURE BELOW NORMAL TEMPERATURES...BUT FOR THE LAST COUPLE DAYS
TEMPERATURE REBOUND TO SLIGHTLY ABOVE NORMAL.
&&
.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
THROUGH 00Z SUNDAY...VFR CONDS EXPECTED THIS EVENING UNDER MOSTLY
CLEAR SKIES. SW-WSWLY WINDS WILL CONTINUE WITH GUSTS TO 20-30KT. A
LOW PRESSURE SYSTEM PASSING TO THE NORTH WILL BRING SNOW SHOWERS
TO THE REGION ALONG A FRONTAL BOUNDARY STARTING AT KMSS AROUND 03Z
AND REACHING KBTV AROUND 06Z WITH CONDS REDUCED TO MVFR. THIS
BOUNDARY WILL CAUSE WINDS TO VEER WEST TO NWLY AND REMAINING
GUSTY. SOME OF THE SNOW SHOWERS COULD DEVELOP INTO IN HEAVIER
BANDS AND BECOME SQUALLY AT TIMES...LEADING TO BRIEF IFR/LIFR
CONDS AND GUSTS OF 35-40KT POSSIBLE. THIS HEAVIER SNOW HAS NOT BEEN
INCLUDED IN THE TAFS AT THIS TIME AND WILL NEED TO BE MONITORED AS
SNOW DEVELOPS. MOST SNOW WILL EASE AROUND 12Z SATURDAY AS THE LOW
MOVES AWAY...HOWEVER BLOWING SNOW WILL REMAIN AN ISSUE AS GUSTY
NWLY WINDS WILL CONTINUE THROUGH THE PERIOD.
OUTLOOK 00Z SUNDAY THROUGH WEDNESDAY...WINDS DIMINISH SATURDAY
NIGHT AS HIGH PRESSURE BUILDS INTO THE AREA WITH VFR
CONDITIONS/CLEARING SKIES FOR SUNDAY. NEXT LOW PRESSURE SYSTEM
MOVES EAST FROM GREAT LAKES AND BRINGS SNOW AND IFR CONDITIONS TO
THE AREA SUNDAY NIGHT INTO MONDAY. MOUNTAIN SNOW SHOWERS POSSIBLE
TUESDAY WITH MVFR CONDITIONS POSSIBLE. VFR CONDITIONS ON WEDNESDAY
WITH HIGH PRESSURE OVERHEAD.
